Although Eugenie and Jack decided they didn't want to televise their wedding, that didn't stop fans from crowding around the streets of Windsor.
Inside the service there was a reading of St Paul's letter to the Colossians, and Eugenie's sister, Princess Beatrice, shared a passage from The Great Gatsby.
The devoted couple met in 2010 when Jack was working as a bartender at a ski resort in Verbier, Switzerland.
The day before they wed in an interview with This Morning they gushed about each other and revealed their connection was instant.
"It was love at first sight," Princess Eugenie shared.
The 31-year-old was so sure of Jack that she called her mum Sarah Ferguson to tell her the news.
"I think I rang my Mum that night and was like 'I've just met this guy Jack' and that was it I think, and this is how it started," she said.
"And I remember being like 'I really, really like this guy, and I really want him to like me, too' and then you gave me this huge windscreen wiper wave and I was like 'right, he likes me'."
This anniversary is the couple's first one that they're celebrating with their son August, who was born on February 9 this year.
Buckingham Palace confirmed the exciting news via their social media channels.
The statement read: "Her Royal Highness Princess Eugenie was safely delivered of a son today, 9th February 2021, at 0855hrs at The Portland Hospital. Jack Brooksbank was present.
